Split Tape‑Wound C‑Core | CRGO Silicon Steel Reactor Core

Split Tape-Wound C‑Core | CRGO Silicon Steel Reactor Core

Our Split Tape‑Wound C‑Cores, also known as cut tape‑wound C‑cores or wound C‑cores, are manufactured from premium CRGO grain-oriented silicon steel strips. The silicon steel is continuously tape wound into a complete rectangular form, processed through high-vacuum annealing, then precisely cut into two matching separable C-shaped halves and supplied as paired sets.

As a popular two‑piece tape wound C‑core option, this reactor C‑core solution enables manufacturers to wind coils independently before assembling onto core legs, greatly lowering assembly labor and production cycle time. Tightly controlled cutting surfaces guarantee consistent mating clearance, reduced noise, lower core loss and reliable inductance stability under continuous working conditions. We offer fully customized dimensions, insulation treatments and batch pairing services for power electronics OEMs.

Two‑piece tape wound C‑core FAQ

Q1: What is the difference between split tape-wound C-core and single-piece gapped rectangular tape-wound core?

A1: Our split tape-wound C-core is cut into two separable C parts and sold as matched pairs for pre-wound coils. The gapped rectangular tape-wound core remains one solid non-split piece; coils must be wound directly through the core window after core production.

Q2: Are your wound C-cores paired and tested before shipment?

A2: Yes. Every set of our two‑piece tape wound C‑core goes through magnetic performance matching. We control mating gap consistency to avoid inductance deviation and extra operational noise.

Q3: Can I customize sizes, coating and material grades for the reactor C‑core?

A3: Full customization is available. We adjust outer size, window dimension, steel grade and insulation coating according to customer drawings and electrical performance targets.

Q4: Can you provide raw material certificates and test reports?

A4: We supply CRGO mill certificates, dimension inspection records and core loss test data for each batch. Documentation can be prepared to support IEC and ISO compliant projects.

Q5: What is your MOQ and lead time?

A5: Flexible MOQ for trial samples and mass bulk orders. Standard sizes have shorter lead times; custom split tape-wound C-core production follows confirmed drawings and schedule.
